Commissioning
LED indicators
STATE LED green Normal operation
Flashing Teach-in operation (for further signal function
see status table)
OUT LED yellow Valid actuator detected
ERROR LED red - Test input activated
- Internal electronics fault
- Invalid teach-in operation
(see status table on Page 18)
In case of an operating fault, the evaluation unit can be reset to the operating state
by interrupting the power supply for approx. 10 seconds.
Teach-in operation
The actuator must be assigned to the evaluation unit using a teach-in function
before the system forms a functional unit. During a learning process, the safety
outputs are open and the door monitoring output is at LOW, i.e. the system is in
a safe condition.
Important!
Ì
Repeated teach-in of the same actuator on the same evaluation unit is not
possible.
Ì
The number of teach-in operations on one evaluation unit is limited to a maxi-
mum of 8
Ì
The evaluation unit can only be operated with the last actuator taught
Ì
A teach-in operation is invalid if:
- the teach-in operation is cancelled before the green flashing LED goes out
- the power supply is switched off during the teach-in operation
Ì
When the evaluation unit is switched on (operating voltage is applied), the
STATE LED signals the number of possible remaining teach-in operations
(see system status table)
Ì
After the eighth teach-in operation or if an "old" actuator is placed against
the read head, the system automatically switches to the teach-in mode. In
both cases, a teach-in operation with a duration of 60 seconds is started;
however, the last actuator remains active (see System Status Table) – a new
code is not taught.
Teach-in function for first actuator
(state on delivery)
1. Apply the operating voltage to the evaluation unit
Ì
green LED flashes fast (approx. 4 Hz)
2. Move actuator to the read head (observe distance < S
ao
)
Ì
teach-in operation starts, green LED flashes slowly (approx. 1 Hz)
3. Teach-in operation completed (after 60 seconds)
Ì
green LED goes out
